RATCHET-WRENCH.

Specification of Letters Patent.

Patented Apr. 1, 1913.

Application filed. December 26, 1911. Serial No. 667,609.

To all whom, it may concern:

Be it known that I, CHARLES E. Erma WORTH, a citizen of the UnitedStates, residing at Las Cascadas, Canal Zone, have invented new anduseful Improvements in Ratchet-WVrenches, of which the following is aspecification.

This invention relates to ratchets and more particularly to that typewhich are used in connection with ratchet wrenches or drills.

The object of this invention is to provide a novel gripping arrangementwhich avoids the necessity of using pawls and toothed wheels which areconstantly becoming broken.

Further objects of this invention will appear as the following specificdescription is read in connection with the accompanying drawing whichforms a part of this application, and in which:

Figure 1 is a side elevation. Fig. 2 is an edge elevation. Fig. 3 is alongitudinal sectional view. Fig. 4 is a detail elevation of the ratchethead removed.

Referring more particularly to the drawing, 1 represents the shank whichis provided with a flattened head 2 having a wedge-shaped outer edge 3.The head is entered between two pivoting plates 4 which are pivoted tothe head by means of a bolt 5 and which are provided with circularaperturecl heads 6 adapted to surround the cylindrical extensions 7 onthe ratchet head 8. This head 8 is provided with a circumferentialV-shaped groove 9 which the wedge 3 fits. The head 2 is of equal widthwith the legs of the plates 4 and when its edges are alined with theedges of the plates 4, the wedge 3 will be free of the walls of thegroove 9. However, when the handle is thrown to one side or the other,the head will be tilted between the plates and the wedge 3 will beforced into engagement with the groove binding upon the walls thereofand preventing rotation of the ratchet head and the extensions 7 Inorder to prevent the head swinging past alinement with the edges of theplates in one movement of the handle and whereby the ratchet head may berotated free when the handle is turned in this direction, the plates 10are pivoted upon thumb screws 11 which bind the plates against the headin such a manner that they may be turned across the plates 4, as shown,or alined with the head 2. When both of the plates are positioned acrossthe edges of the plate 4, the head 2 has no relative movement withrelation to the plates 4 and when both plates 10 are alined with thehead, the head 2 has relative movement in both directions with relationto the plates 4. It will therefore be seen when one of the plates isalined with the head and the opposite plate turned across the head andthe plates 4, the head 2 will have relative movement only in onedirection so that the plates 4 may be rotated idly around the ratchethead 8 in one direction and the wedge 3 positively engaging the same inthe opposite direction of movement. Each extension 7 is provided with asocket which may either be adapted to receive a nut or a drill or anyother similar tool and each head has a set screw 12 for locking the toolin the socket.

Having thus described the invention, what I claim as new, is

1. A device of the class described comprising a pair of plates, amember-rotatably mounted therein, a head on the member arranged betweenthe plates and having a V shaped groove, an operating handle pivoted tothe plates, means carried by the handle and adapted to wedge in thegroove upon movement of the handle in either direction, means pivoted onthe handle for preventing relative movement of the handle and plates ineither direction and means for locking the last named means in operativeor inoperative position.

2. A device of the class described comprising a pair of plates, asocketed receiving member journaled therein, a circular head on themember arranged between the plates and having a V-shaped groove, anoperating handle pivoted upon the plates, an extension thereon having astraight wedge shaped end adapted to engage the groove, In testimonywhereof I afllx my signature turn buttons pivotally mounted upoln the inpresence of two Witnesses.

0 osite sides of the extension and a apted td projeot across the platesto one side of CHARLES WATERWPORTH 5 the pivotal pin of the handle, andset screws Witnesses:
